羧肽酶Y 来源于酵母, ≥50 units/mg protein
Product Name： Carboxypeptidase Y from yeast
CAS号:9046-67-7
介绍： Carboxypeptidase Y is a glycoprotein exopeptidase of the 'acid' and 'serine' class. Carboxypeptidase Y has a broad amino acid specificity, including proline and amidated amino acid residues.
用途： Carboxypeptidase Y has a broad specificity and is stable in urea. Hence, this enzyme is not like other carboxypeptidases and can be used for sequence analysis. Due to its amidase action, this enzyme might be applied to the sequence analysis of peptides having amidated COOH-terminal groups such as oxytocin and vasopressin.
贮存： 储存温度 -20°C
生化和生理学机理： The glycoprotein has a molecular weight of about 61,000, has a nitrogen content of 12.74%. It is a single polypeptide chain of 442 residues with 16 residues of glucosamine in the carbohydrate moiety. Lysine is at the NH2 terminus and -Asp-Ser-Thr-Leu is the COOH-terminal sequence. The principal action of the enzyme is to remove COOH-terminal residues from polypeptide chains. It is used as a vacuolar marker enzyme for studies on protein transport and localization.
